I've lived in Switzerland for 10 years now and I'll only leave kicking and screaming. It's a fab place, despite one or two odd laws.
I have outside my door what can only be described as a cycling motorway which gets me to work. In fact it was requisitioned temporarily by the local bendy buses while the road was being resurfaced, it's that good!
The velo vignette is numbered and the idea is you keep the other half with the same number so there is some chance of you being reunited with it if you report it. Personally, I wouldn't leave a bike unlocked as they tend to be "borrowed" and abandoned rather than actually stolen as such.
As for the suicide, every man does national service and when complete remains a reserve, which means they keep a gun and attend target training I think twice a year. I think the numbers involve simply are a case of opportunity, it's a lot easier than a trip to the local railway tracks.
Actually until Gordon Brown wrecked the economy and destroyed the value of the pound, it was actually pretty cheap to live here, certainly lower than outer London. Anyway, wages are 2-2.5 times that of the UK and you pay less than half the tax.
And we have mountain biking with real mountains, not those pimples you have in the UK!
